Abstract: A centrifuge rotor (10) is provided in which an array of loops (75) is circumferentially provided about the exterior of the hub (12). The loops having openings (76) therein which receive a hook-like appurtenance (64) mounted on a sample container (48) and support the same for pivotal rotation from first to second position. The loops (75) are resiliently mounted to the hub such that increased centrifugal force is accommodated by radially outward deflection of loops. The loops may be torsioned to untwist as the carrier pivots from the first to the second position.

Abstract: A sample processor card for use with a centrifuge in which the direction of centrifugal force can be altered at will, wherein the card includes a supply of chemical reagent and inlet means for supplying a chemical sample to the card. The sample is advanced under centrifugal force through capillary means to sample measuring means, and the measured sample is then mixed with reagent to permit a chemical test to be carried out on the reagent, all under centrifugal force.

CPC classification number: B03B5/00
Abstract: The method described is useful in field flow fractionation techniques for reducing separation times and improving the convenience and accuracy of measuring sizes or molecular weights of particulates. In field flow fractionation, the particulates (particles or macromolecules) are subjected to a force field and a mobile phase while passing throught a flow channel. This filed strength is decreased exponentially as a function of time. Alternatively the flow velocity is increased exponentially as a function of time. The initiation of the change in field strength or flow velocity may be delayed a period of time. If this time delay is made equal to the time constant of the exponential decay, the range of particulate retention time that is linearly related to the logarithm of the particle size or molecular weight is increased. An apparatus for implementing the method is also described and includes a function generator 100 for providing the desired exponential decay and delay time to a speed control 102 controlling a motor 104 of a centrifuge bowl 26.

Abstract: A long, thin annular belt-like channel is designed for use in sedimentation field flow fractionation. The channel has a generally rectangular cross-section and a width to thickness aspect ratio (B to w) lying in the range of 3-50 to 1. The channel may be formed of a flattened capillary tube. The ratio of the thickness of the channel to the characteristic height of the particles to be separated (w to 1) is greater than 5 to 1.

Abstract: A separate capping assembly for a centrifuge tube includes a stopper having a plug adapted for close fitting receipt on the interior of the neck of the tube being sealed and a complimentary tubular sleeve sized for close fitting receipt over the exterior of the tube neck. The sleeve is responsive to a radially inwardly directed force by deform- ably crimping to compress the material of the neck of the bottle into an annular seal defined between the plug and the sleeve. The annular seal so formed resists fluid leakage from the interior of the tube during centrifugation of the tube.

Abstract: A top loading swinging bucket centrifuge rotor is characterized by the provision of a sample container knife edge pivot element (100) which engages the sample container (48) along a substantially line contact as the container pivots from an initial to a second position. The container (48) may be inserted into the rotor (10) such that any diametrical dimension thereof is aligned with the line contact, thus avoiding the necessity of orienting the container (48) with respect to the rotor (10). A guide slot for guiding the motion of the container (48) is disposed radially inwardly of the pivot elements (100).
